This invention relates to automobile doors and the object of the invention is to provide an automobile door equipped with a screen panel in addition to the usual window glass panel together with means whereby both ofsaid panels may be actuated through the instrumentality of a single operating handle.

Another object of the invention is to provide an arrangement of parts enabling either la the screen panel or the window glass panel to be raised or lowered irrespective of the position of the other panel.

Other objects, advantages and characteristie features of the invention as wellas the details of construction and arrangement of parts characterizing thev embodiment disclosed herein will be more readily understood from the following detailed description and accompanying drawings in which,

Figure 1 is a view partly in side elevation and partly in vertical section of an automobile door equipped with my invention.

Figure 2 is a longitudinal vertical sectional view taken along the line `2--2 of Figure 1 and,

Figure 3 is a transverse sectional view taken along the line 3-3 of Figure 1.

Referring more particularly to the drawings, 5 designates an automobile door having its lower portion in the form of a casing 6 ancL its upper portion provided with a window opening 7. A glassipanel 8 and a screen panel 9 are mounted in suitable guide ways 10 so as to travel vertically from a lowered position within the casing 6 to an elevated position obstructing the window opening 7. In lowered position bothpanels rest on supporting shoulders 11 formed in the lower portion of casing 6 above the bottom wall 12 whereby a clearance or pocket 13 is reserved between said wall 12 and the lower edges of the panels. Both the panel 8 and screen panel 9 have a driven mea-ns connected therewith, and are adapted to be selectively operated by a single driving means.

The driven means for the glass panel 8 includes a block which is secured to said panel and through which is threaded a ver- 0 tically disposed screw 15 having its terminals mounted in suitable bea-rings 16.1v Near the upper bearing`16 this screw is provided with a worm gear 17 adapted at times to' be engaged and driven by a worm 18j fixed to :f: a rotatable spindle 19 passing slidably 55 through a suitable bearing 20 forme'din the inner wall of they casing 6, said spindle'v -19 being equipped atits outer end 'with an operating crank 21. 1

The driven means for the panel 9 includes 60 a transversely extending shaft 22 journalled at one end of the pocket 12 and provided with a-relatively long crankV arm 23y adaptedx to engage the lower edge of the screen panel9. At the end remote from crank arm 23 the 65 shaft 22 is provided with a worm 24 meshing with a worm wheel 25fixed to thelower end of a vertically extending inclinedshaft 27. Shaft 27 isV mounted in suitable bearings 28 and is equipped at its lupper end 70 with a worm gear 29 adapted at times to be engaged and driven'bfy the worm 18 of the crank operated spindle 19. In otherrw'ords the lworm 18 and the crank operated spindle 19 constitutes a single driving means, adapt- 75 ed to be singlyand selectively used in conjunction with the panel driven means above described.A As shown tov advantage in Figures 2 and 3 the relative arrangement of the shafts 15 and27 and the spindle 19 is such so thatthe wormV of spindle 19 maybe selectively engagedwith either of thek worm gears 17 and29 by sliding the spindle inwardly or outwardly. v Y

Whenthe parts are in theposition shown in Figure2 it will-be apparent that by turni ing'the crank A21,in` the proper direction the crank arm 23 of shaft 22V will be raised to carry-the screen panel 9 upwardly to a positionv obstructing the opening 7. When it is desired to raise the window panel 8 lthe spindle v19 is shifted inwardly to mesh the worm 18 with the gear 17. c

While no meansare shown for securing the screen panel 9 in raised position it will be ,95 understood that any of the well known mechanical expedients may be resorted to fo this purpose.

Having described what I now conceive t0l be a preferred embodiment of the invention ,100

'it will be understood that various changes may be resorted to within the scope and spirit of the appended claims.

What I claim is: Y

1.k An automobile door having a window opening formed in the upper half thereof and a casing 'in the .lower half thereof, a glass panel and a 'screen panel adapted to be housed in said casing or to be projected `therefrom to an elevated position within said window opening, a pair of rotary shafts mounted in said casing, each of said shafts being connected to one of said panels by means functional to raise or lower `'the panel dependent on the direction of rotation of said shaft, Yan operating handle journalled in one wall of sai'dcasing 1and a drive gear fixed to said handle and adapted to be selectively engaged with driven -gears carried byl said shafts to eii-'ect independent actuation of said panels.

-An automobile door having Ja window opening formed in the upper half thereof and a'casing formed in the lower half thereof, the inner side surfaces of said door being .provided with parlallel vguide `channels extending from lthe lower portion of said-casing to the `upper portion of the window opening, a glass .panel and a windowscreen panel slidably mounted in said :panels and adapted toV occlpy a -lowered position within said casing oran elevated position Ywithinwsaid window opening, a pair of driven; Vgears rotatably mounted in said casing, a connection between each gear and one .of said panels functional l to raise or lower the panel dependent upon the direction of rotation of sai-d gear, a hansignature.

dile memberj ournalled ina wall of said casing and .a drive ,gear` vfixed to said handle member and shiftab'le into engagement with either of said driven gears'. i Y

" '3; An automobile .door hav-ing a window openingA formed in the upper half `thereof 'anda casing inthe lower half thereof, a glass panel and a screen panel adapted to be housed in said casing or to be projected therefrom to `an elevated position within said window opening, a .driven means connected to each of said panels, asingle :driving-means, "and Y means for causing the motion of the driving means to 'be transmitted to either ofpsaid driven means independently; of the other, all

these elements beingxconeealed within `the door casing'. Y

n testimony whereof I hereunto vaix my nMoRY of. BULLis.
